An audio processing method and system for a seat headrest audio system, the audio system including at least two speakers positioned on opposite sides of the headrest, the method including detecting a position of the user's head and adjusting a first set of parameters of at least one audio processing operation as a function of that position. The method includes determining a user characteristic and/or temporary state of the user, selecting an audio settings profile related to that characteristic, the audio settings profile including a second set of prerecorded audio profile parameters, and adjusting a third set of audio parameters effectively applied to control the audio rendering of each speaker, based on the first and second sets of parameters.

A speaker system is provided having a primary speaker module configured to communicate with an external audio device and having a speaker output face and a back surface, and a secondary speaker module in signal communication with the primary speaker module and having a speaker output face and a back surface. The primary speaker module and the secondary speaker module combine in at least two configurations, a first configuration in which the primary speaker module and the secondary speaker module are connected at their back surfaces and their respective speaker output faces face opposite directions, and a second configuration in which the primary speaker module and the secondary speaker module are side by side and their respective speaker output faces face substantially the same direction.

An audio processing apparatus comprises a receiver (705) which receives audio data including audio components and render configuration data including audio transducer position data for a set of audio transducers (703). A renderer (707) generating audio transducer signals for the set of audio transducers from the audio data. The renderer (7010) is capable of rendering audio components in accordance with a plurality of rendering modes. A render controller (709) selects the rendering modes for the renderer (707) from the plurality of rendering modes based on the audio transducer position data. The renderer (707) can employ different rendering modes for different subsets of the set of audio transducers the render controller (709) can independently select rendering modes for each of the different subsets of the set of audio transducers (703). The render controller (709) can select the rendering mode for a first audio transducer of the set of audio transducers (703) in response to a position of the first audio transducer relative to a predetermined position for the audio transducer. The approach may provide improved adaptation, e.g. to scenarios where most speakers are at desired positions whereas a subset deviate from the desired position(s).

A multi-driver multi-channel single enclosure Height-Channel (e.g., ATMOS® or DTS-X®) enabled soundbar loudspeaker system 260 uses a novel signal processing system, driver mounting configuration (310L, 310R) and method to provide a high fidelity home theater listening experience, in a manner which relies on a new method for cancellation of unwanted direct (not ceiling-bounced) radiation of the Height-Channel (or virtual height envelopment) channel's sound 213DS.

A method for playing audio data, includes: detecting a number and position relationships of associated audio playback devices; performing audio signal processing on audio data to be played based on the number and the position relationships to obtain an audio signal matching the number of the audio playback devices; and playing the audio signal through the audio playback devices.

The present disclosure relates to loudspeaker devices and configurations. In at least one embodiment, a loudspeaker includes a housing structure having a multi-sided cross-sectional profile, a first speaker configuration coupled to a first face of the housing structure, and a second speaker configuration coupled to a second face of the housing structure. The first face of the housing structure and the second face of the housing structure may be adjacent to each other, and the first face of the housing structure and the second face of the housing structure may be substantially planar, in one or more examples. The loudspeaker may further comprise a controller configured to rotate the housing structure. For example, the housing structure may be rotated about a central axis of the housing structure. Further, the housing may be an elongated triangular structure in at least one example.

An apparatus for generating a description of a combined audio scene, includes: an input interface for receiving a first description of a first scene in a first format and a second description of a second scene in a second format, wherein the second format is different from the first format; a format converter for converting the first description into a common format and for converting the second description into the common format, when the second format is different from the common format; and a format combiner for combining the first description in the common format and the second description in the common format to obtain the combined audio scene.

Disclosed herein are system, apparatus, article of manufacture, method and/or computer program product embodiments, and/or combinations and sub-combinations thereof, for identifying electronic devices in a room using a spread code. In some embodiments, a first electronic device receives a spread spectrum signal from a second electronic device over an audio data channel. The first electronic device determines a time of receipt of the spread spectrum signal based on despreading. The first electronic device calculates a distance between the first electronic device and the second electronic device based on the time of receipt and a time of transmission. The first electronic device determines the second electronic device is not in the room with the first electronic device based on the calculated distance.

A noise cancelling soundbar that may be integrated into a piece of furniture, such as a bed, comprising one or more loudspeakers, an integrated power amplifier, one or more microphones, an audio input communication module, and an active noise cancellation module. After receiving an audio input signal from a media source, such as a TV or smartphone, the noise cancelling soundbar may produce an amplified output signal. By using its microphones and active noise cancellation technology, the noise cancelling soundbar may, in addition to reproducing input audio via its loudspeakers, generate negative sound waves which destructively interfere with ambient noise to allow users to listen to audiovisual media without disturbing non-listeners in the area, and without using headphones.

Low-latency audio networking is disclosed. In one embodiment, an example playback device includes a processor and memory having stored thereon instructions executable by the processor. The example instructions are to cause the first playback device to perform functions comprising: receiving audio information; selecting a first frequency channel of a first spectrum based on a threshold latency associated with the audio information; transmitting to the second playback device via a second frequency channel of a second spectrum, control information that identifies the first frequency channel of the first spectrum; and transmitting to the second playback device via the first frequency channel of the first spectrum, the audio information to be played by the second playback device.
